Distribution of interstitial stem cells in Hydra [PDF]
The distribution of interstitial stem cells along the Hydra body column was determined using a simplified cloning assay. The assay measures stem cells as clone-forming units (CFU) in aggregates of nitrogen mustard inactivated Hydra tissue.

The properties of nerve cell precursors in hydra [PDF]
Two signals, the head activator and an injury stimulus, control differentiation of nerve cells from uncommitted stem cells in hydra [Th. Holstein, H. C. Schaller, and C. N. David, (1986) Dev. Biol. 115, 9–17].

Spatial pattern of nerve differentiation in Hydra is due to a pattern of nerve commitment [PDF]
The pattern of nerve differentiation along the body column of Hydra was investigated. Nerve precursors in late S phase were labeled with [3H]thymidine and their distribution compared with that of newly differentiated nerves.

COMMITMENT DURING NEMATOCYTE DIFFERENTIATION IN HYDRA [PDF]
Nematocytes in Hydra differentiate from interstitial stem cells. Desmonemes differentiate mainly in the distal half of the body column while stenoteles differentiate predominantly in the proximal half.
